My invention relates to improvements in drawing apparatus. 3 and 4 arethe upper spinning, doubling or similar textile frames, ends of tubularspindles of a two-row iyer and more specifically in spinning frames forspinning frame, 5 and 6 the guide members, producing yarn ,from coarsefibrous mateand 7 and 8 the threads. The means of rials, such as sisalor manila hemp, at commounting the guides have been omitted for 55paratively high speeds. the sake' of. clearness, asthey may be of anyUne object of my invention is to provide conventional design and requireno descripupon a guiding member over which the thread tion.

Another design of the projections is illus- 'trated in elevation in Fig.46- and in longitudinalsection ingF'ig. 7 of the drawing. Small circularor spherical projections are here distributed over the face of the guidemember and again exert a kneading action upon the thread. The spacesbetween these projections likewise arrest projecting fibres and promotetheir being twisted into the thread.

The broad idea underlyin-g my invention is that all loose fibresprojecting laterally from the body of the thread find a certainresistanceA against their longitudinal motion towards the inletintofthe' tubularL spinning.

spindle, and that on the other hand` theA re- A sistance against theirmotion towards the guide the threa thread is made aslow as possible. Theprojections and grooves vvor teeth and gaps on the guide member shouldtherefore in cross-section have a closer resemblance to the teeth of asaw than to those of a rack.

In any case it is desirable that the guiding faces should commence asclose as possible to the delivery roller and extend as far as possibleup to the entrance opening ofthe spinning spindle.

The guiding member may consist of a metal casting, porcelain or thelike, but it will be understood that it may be die pressed of sheetmetal of moderate or fine gage or produced in any other suitable manner.

Various modifications and changes may be madelwithout departing from thespirit and the scope of the invention.

I claim as my invention:
